在 4 x 节点集群中使用 ActiveMQ Artemis 2.14 设置，并且消息重新分发的行为不符合我的预期 - 寻求一些帮助来阐明它应该如何行为，即我的配置是否错误或者我只是期望系统做一些它不做的事！
集群充当为多个应用程序提供服务的中央消息传递中心。集群中的所有节点都配置相同。各种客户端应用程序是消费者、生产者或两者兼而有之，通常也会根据需要进行集群和扩展。
我遇到的问题情况的一个例子是一个消费者应用程序，它只有两个节点，每个节点运行一个消费者线程，因此它使用的队列上只有 2 个消费者 - 即 4 个节点中的 2 个（最多）会有消费者。生产者应用程序将消息发送到队列，并且由于各种原因，可能会出现消息最终到达没有消费者的节点的情况。因为生产者客户端负载似乎并不“喜欢”带有消费者的节点（可能会就此提出一个单独的问题！）或者可能是因为消费者应用程序可能会因维护或其他原因而停机，但生产者应用程序仍在运行并发送消息。我们为队列配置了“重新分配延迟”（值为 600000），我们预计这些消息会在该时间之后自动移动到具有消费者的其他节点之一，但这似乎并没有发生.
回顾文档后，我意识到它说“......延迟（以毫秒为单位）在最后一个消费者关闭之后在重新分发消息之前在队列上......”。这是否意味着，如果特定节点上从来没有任何消费者（我猜是自上次重新启动以来？），那么到达该节点的消息将永远不会被重新分发？如果有的话，有什么建议可以处理这种情况吗？
我的broker.xml（经过修改以简化并匿名化）
谢谢！
